Rout HTTP request from intranet through proxy and out

[asj123]

We have an application running on the intranet that requests a xml feed from the internet. Traffic from the intranet needs to go through a proxy. Preferably, we don't want to programmatically change the client (as it's not our code area). I heard that there might be a way to set up php.ini to let http request go through a proxy.

Does anyone have an idea about this? Or is the only way to programmatically set the proxy? Can I possibly use fopen() with proxy?

Thanks for any help on this

I found this on a site

putenv("http_proxy=$PROXY_URL:$PROXY_PORT");
$result = shell_exec("wget -q -O - $url");

I am wandering if I can use something like this, but I'm not familiar with the http_proxy environmentvariable.

Would this be a way to solve the problem? Any experience on this?

Ok, if all the above questions were to complicated or unclear, I have now the following question.

We would rather not prefer to do any changes in the application. I have heard that you can set something like a http_proxy variable in php.ini.

I have no experience on this.
Could someone please help me on this. Is this true? How can I specify it.

Thanks again
